Fly ash bricks are used for the construction of various types of buildings such as: Factories. Warehouses. Power plants.Fly Ash bricks are made of fly ash, lime, gypsum and sand. The raw materials are blended in desired proportions in a Pan mixer for 4-5 minutes and compressed. They undergo curing for a minimum of 14 days and are then air dried for 7 days. Strength of these bricks can be engineered by varying the compositions.The fully automatic machine comprises of an elevator, lowerator, finger car and cuber, that together form the automated handling system. Further, in a semi-automatic machine curing is done manually in an open space.Fly ash bricks are uniform in shape and size in comparison to burnt clay brick, therefore, require less mortar in brick work and finishing work resulting saving of cement mortar. 3- As, fly ash brick are machine made, quality control is better in comparison to burnt clay bricks.
